Ah Chao was at the iron smelting base, and Li Zhao handed him the drawings and methods for manufacturing main components such as steam engine cylinders and control valves.
Ah Chao took one look at it and took it over without saying much.
Li Zhao hadn't been to the Iron Smelting Base for a long time. This trip came at the right time, so he went inside to inspect it.
Since the establishment of the base, he has given Ah Chao many secrets, and he would like to see if the craftsmen in the base have mastered them.
Walking inside, the base that appeared in front of you was simply eye-catching.
I just came back from the weapons manufacturing department of the imperial court. Compared with this, the weapons manufacturing department is simply weak.
This is what an iron smelting base should look like.
There were large furnaces, mountains of iron ore, dozens of blowers, machine tools and other equipment not far away. Beside it, you could also see other elemental mines. Although the quantity was smaller, Li Zhao was surprised.
He once told A Chao about the appearance and color of various mines and asked him to send people to search for them. It seemed that A Chao was very interested.
Looking next to the furnace, something similar to coal appeared, but it was very dark. Li Zhao's eyes lit up. This was coke. When he gave Ah Chao the secret book of smelting steel, he asked Ah Chao to try to refine it. Coke, it looks like he succeeded.
Of course, since steel can be made, it must have been successful very early.
Coke is obtained by carbonization of coal at a high temperature of about 1,000 degrees Celsius. It is difficult to reach a high temperature of 1,000 degrees Celsius according to Daqin's current calcination technology. However, after Li Zhao gave the manufacturing drawings of the blower, the situation was different. .
It is difficult for an ordinary charcoal fire to reach a thousand degrees, but with the help of wind, it is much easier.
The temperature generated by the combustion of coke is very high. Once the coke is distilled out, it is not difficult to continue to produce it. With coke, it is much easier to turn iron ore into molten iron.
This is something that Da Qin's current technology cannot do.
Looking to the side, there are finished steel products, which are being piled up. At this moment, the major forgings are in full swing, and it seems that they are about to be mass-produced.
On the other side, wires were also manufactured. Although they were larger than the ordinary wires in previous lives, they did not hinder their use. The craftsmen also mastered the skills and wrapped a layer of rubber on the surface of the wires.
"Uh-huh!"
Li Zhao nodded with satisfaction.
With steel and wires in hand, hydropower stations could soon be under construction.
"You need to produce these parts as quickly as possible. The hardness and toughness must be ensured. The dimensions must be precise and the errors must be minimal."
There must be emergency contact between the cylinder and piston of the steam engine to prevent steam leakage, so it must be particularly precise. However, Li Zhao was not worried. When making firearms, he told Ah Chao the manufacturing method and fine scale of the scale. , with the engraved ruler, the error will not be too large.
Ah Chao nodded.
Soon, Li Zhao left.
In Chang'an Township, an uninvited guest came. This man was old and had a haggard face, but his eyes were filled with deep thoughts, as if there was an inextricable knot lingering around his body.
Regardless of the fatigue from the past few days, he dragged his not-so-straight body towards Chun Yuyue's farmland.
This person is none other than the clever Confucian old man.
In the field, Chunyu Yue was still hoeing grass, and his body was still stooped. The days of becoming a farmer had made him exhausted and made him less tempered.
"Old man Chunyu, tell me, is it intentional? Really?" Old Man Lingdongru's voice came over before he arrived.
"Are you trying to kill me? Just because of such a little prejudice, do you have the nerve to damage our long-standing friendship?"
"You old fool, I'm not done with you."
The old man started to curse and came directly towards Chunyu Yue.
Chunyu Yue raised his head, saw the angry figure, smiled calmly, did not continue hoeing, but took a few steps, picked up the hoe from the side, stumbled back to the original place, and threw it aside.
"Old immortal, why don't you speak? Has being a farmer made you stupid?" Seeing Chunyu Yue, he didn't say a word and didn't even bother to look at him twice. He was smart and old-fashioned.
Finally, Chunyu Yue smiled a little and spoke: "I am about to be buried, but I am still so impatient. Come, come, help with weeding and calm down."
He simply picked up the hoe and threw it away.
Elder Ling Dong was very angry and kicked the hoe aside.
"Go away, tell me quickly, what do you mean by that?"
